How to make pptx animations work in LibreOffice-impress?

Hi. I love watching these pptx animations on theartofbattle.com, but i have to use wine and powerpoint viewer (i run a debian), just to make animations work. Libreoffice does open the file, but animations and slideshow do not work properly, a lot of stuff is missing. So if anyone could point me to the solution, that would be awesome.
